4. Technical data
Switching voltage: 250 V AC
220V DC max.
Switching current: 6A AC
0.12 A DC max.
Power rating: 1500 VA max.
1 mW min.
5. Operation
• Connect the relay to the “Digital Outputs”
socket of the 3B NETlog
TM equipment using the
supplied mini DIN lead. It responds to digital
output A.
• Preferably use 4-mm safety leads for the re-
maining electrical connections to the experi-
ment set-up.
6. Sample experiment
Measuring the discharge of a capacitor with the
basic experiment board
1 3B NETlog TM U11300
1 Relay U11368
1 Basic experiment board U11380
Various experiment leads with 2-mm and 4-mm
plugs

• Consult the instructions for the basic experi-
ment board U11380 for the electrical connec-
tions between the relay and the experiment.
• Select one of the analog inputs (A or B) on the
3B NETlog
TM module and follow the instructions
for the board regarding the experiment on ca-
pacitor discharge. All necessary output value
settings are specified here.
• Conduct and analyse the experiment.
